What Is The Difference Between Fulvic Acid And Humic Acid? Which Is Better?

Jul 12, 2018


Humic acid is divided into brown humic acid,yellow humic acid and so on.Humic acid is the remains of plants and animals,mainly is the remains of plants and through the decomposition and transformation of microorganisms,a series of changes and geochemistry,the physical process of accumulated a macromolecular organic weak acid mixture,according to the different solubility in different solvents and color,can be divided into fulvic acid, brown rot,black rot acid and green four rot acid.

They are characterized by:

Fulvic acid:it is highly acidic and has a good complexation effect on metal ions.  

Black fulvic acidit moves slowly in plant body,stimulates slowly,and is easily absorbed by plant surface,promoting root growth.

Brown fulvic acid:contains the oxygen active group content medium, moves slowly in the plant body, the stimulation medium.

Humic acid is widely found in soil, peat, lignite, weathered coal, sea, lake and swamp.The total amount of humic acid in soil is the largest, but the average content is less than 1%. The total amount of salt water is also quite large, but the concentration is lower, which is impossible to develop as a resource. The most promising sources of humic acid for exploitation are some geothermal coal, such as peat, lignite and weathered coal, whose humic acid content reaches 10-60%.

Fulvic acid potassium is an effective and macromolecular organic compounds, is minimum molecular weight of humic acid, reactive water soluble part of the highest levels, the interaction between functional groups, reflecting the variety of specific physical and chemical properties, after entering the animal and plant body, can play a variety of physiological functions, inhibit or activate enzymes and role in the metabolism of plant and animal organism, reflects the obvious stimulation, through the regulation of endocrine hormone play a role of treatment and improve the body's immune function.


Fulvic acid has the general characteristics of humic acid, namely:

One is that its molecular weight is small and it is easy to be absorbed and used by organisms.

Second, it has more functional groups than normal humic acid, which has greater physiological activity and stronger complexation ability to metal ions.

Third, humic acid can be directly soluble in water, the aqueous solution of these salts becomes basic, while yellow humic acid can be directly soluble in water, its aqueous solution becomes acidic.


Main functions:

Fulvic acid application in agriculture to the current domestic source of potential technology in the world mainly adopts fulvic acid and biological fermentation product of the combination of new technology, and in the production process, application of compound bacteria fermentation technology and one-step extraction of fulvic acid combined with technology, this will make the fulvic acid used in agriculture shows strong vitality.

Current domestic production ZengChanSu mainly focused on the application and efficient plant foliar fertilizer, organic liquid fertilizer and plant auxin, etc., technical content is low, urgently need to improve the fulvic acid application of high and new technology in agriculture.  

Research shows that fulvic acid in the role of the agriculture, the main soil improvement, improve fertilizer effect, stimulating plant growth, increase the plant resistance, improve the quality of the plant, concrete is discussed regarding the domestic typical control effects were as follows;  

1.Improve the structure of the soil group, loosen the soil, improve the soil's fertilizer conservation ability, adjust the pH value, reduce the content of heavy metals in the soil, and reduce the harm of salt ions to seeds and seedlings.  2.Nitrogen fixation, phosphorus removal and activated potassium. In particular, the synergistic effect of potassium fertilizer is particularly obvious, which can increase root and seedling, resist heavy stubble, resist disease and improve crop quality.

3.Strengthen the adhesion and rapid absorption capacity of plant roots, especially for physiological diseases caused by the lack of trace elements.

Potassium humate is a kind of aromatic hydroxy carboxylate with high molecular imhomogeneity.      

Appearance: black powder solid, soluble in water, alkaline, containing hydroxyl, carboxylate and other active genes.      

Main specifications:

Enterprise, it required of the plant nitrogen, phosphorus, potassium and other elements, can be a multifunctional efficient compound fertilizer, applied for soil improvement and plant production stimulation and slightly -- have certain effect. Industry: drilling mud treatment agents, ion exchange agents, wastewater treatment agents, heavy metal adsorbent, etc.

Main functions of humic acid:

A. Using humic acid, can change too high salty, alkali in the soil, soil grain of highly fragmented, with poor soil structural properties, promote the formation of soil aggregate, make them in good condition, so that plant root growth and development in good conditions.

B. The application of humic acid can loosen the cultivated soil, destroy the accumulation of salt, reduce the salt content of surface soil, play the role of salt isolation, raise the seedling rate, reduce weak seedlings and dead seedlings, and make plants grow healthily. 

C. Humic acid has a high amount of cation transformation, more than 10 times higher than normal soil. When applied to the soil, the adsorption capacity of the soil to the anion increased significantly and the surface salt content decreased. 

D. Saline land especially high alkali soil PH value (9.0 or above), directly harm crop growth, and even cause death, the PH is too high but also affect the soil phosphorus, iron, manganese, boron, zinc and other nutrients is effective. Acid and humic acid PH value of 6.8, can neutralize alkaline, reduce eliminate alkaline the harm of soil and plants, the low yield improved saline-alkali, create a good soil conditions for crop seedling growth.

Summary:

1. humic acid in agriculture of the "big five" (improve soil, increase fertilizer, stimulate growth, enhance the art and improve quality) has been guiding the application and progress of humic acid in agriculture. 

2. Fulvic acid is a kind of humic acid product with wide range of application and high economic benefits. It is now used in plant growth agents, anti-stress agents, fluid fertilizers and medicine Pharmaceutical, cosmetic and other aspects still have a large market and competitive advantage.   

3. The "four-agent function" of yellow rot acid in agriculture (drought-resistant agent, growth regulator, pesticide slow-release synergist and chemical element complexing agent) is a classic, and it is a unique drought-resistant agent.
